T0 ALL WHOM-IT MAY CONCERN:

: Be it known thatl, F. S. WYMAN, of Chicago, in the-county of Cook, inthe State of Illinois,'have invented i an Improved Can-Opener; vand I dohereby declare that the following is a full and exact descriptionthereof,

reference beingvhad to the accompanying drawings,and to the letters ofreference` marked thereon, making a part of this specification, inwhichl Figure 1 is a longitudinal sectional Aelevation ofmy invention.

Figure 2, a view of one'of the knives detached from the sliding plate.Figure 3, a side elevation.

The nature of' my invention consists in the attachment of asharp-pointed knife to the adjustable plate of circular-can opener, bymeans of which square. and longitudinal openings may he made infruit-cans with the vsame tool which iA used to make round holes. Thisarrangement is especiallyl desirable, for without it a hole cannot bemade which has a greater diameter-than the thickness of the can, andas'such a size is entirely too small for many purposes, such as forsardireboxes&c.,"the circular opener is not generally used, but by theattachment of aside knife, a morer complete tool is provided, and onewhich will fully answer all practical purposes.v l i i In order to givea correct understanding of my invention, I have marked correspondingparts with similar letters, and will'notv give a detailed description.

A represents a slotted plate, fitted in a handle, B, and having apointed pivot, E, used asV an axis for the knife'I), the same asin thepatent of S.D. Lecompte, of September 19, 1865, and has a plate, F,arranged to `run in' the slot B and support the knife I), held in placbya set-screw, H, when moved in said slot to suit the semi-disirreter ofthe opening tobe made. This plate Elias a side knife, C, arranged to fitVclosely against the side of the slottedplate A, and is used to makerectangular openings lin cams lwhen circular ones will not answer thepurpose, and may beset to or from the end'ot= said plate A, as mostconvenientfor the operator's use. The plate F and knife C should bemade; of a single piece of steel, and with a nib,K, to guide it in theslot B, as seen at fig. 1, and the knife should bc tempered so'as'tohold a good edge.'

It will be seen from this description that the knife G is not intheway'of-operating the knife D, and that itcan be set near enough to theend 'of plate to permit 'the handle B to move v over a large ilatsurface .tvithlo'ut interfering with the hand.

Having thus* described my invention, I doi not' claim the device hereindescribed for making circular openings, it having been patented by' S.D. L ecompte, September 19, 1865; 'neither do'I claim broadly theknifeC,

vas a similar d evice was patented by S. P. Chapin, July 17, 1866; but

4operate substantially as herein set forth.

what I do claim, and desire to secure by Letters Patent of the UnitedStates, is- The knife' C, rigidly attached to th-e adjustable plate F ofa circular-can opener, and constructed to s. WYMAN.
